subtract change color of faces 1

[RSilva]

Hello

I have a problem with colors
When i do a subtract, few faces that are in contact with the subtrated body change color and become translucent
Other problem is when i create faces or radius, sometimes is with one color, sometimes is with another color.
How can i solve this?
